ISAAC H. ASIRE, OF FOREST, OHIO.

ROOF.

SPECIFICATION forming part of Letters Patent No. 361,974, dated April 26, 1887.

Application filed January 6, 1887. Serial No. 223,509. (No model.)

To all whom it may concern:

Be it known that 1, Isaac H. ASIRE, a citizen of the United States, residing at Forest, in the county of Hardin, State of Ohio, have invented certain new and useful Impr0vements in Roofs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to sheet-metal roofs; and the object of the invention is to provide a roof the joints of which may be formed without solder, and which may be easily constructed, and which will beseenre and absolutely water-tight.

With these general objects in view the invention consists in certain features of construction, hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure l is aperspective of a portion of a roof constructed in accordance with my invention. Fig. 2 is a perspective of the cap or covering for the joint. Fig. 3 is a vertical section on the line X X of t-hejoint. Fig. 4 is a plan view of the blank (before folding) from which the cap or covering is formed.

Like letters of reference indicate like parts in all the figures of the drawings.

A represents the sheathing, and B the sheet metal plates, which are joined by the transverse seams B, by folding, or, if preferred, solder may be used, and the lower ends of which are bent down over the sheathing or eaves and secured thereto by nails, as usual in this class of roofs. The platesB are cut away at their corners and struck up to form flanges B at each side thereof, the flange of each plate coming against a similar flange of an adjacent plate. I v

0 represents a metal clip secured to the sheathing, as at G, by means of nails, and bent upwardly to form the bifurcated retainingflange 0 These are placed at suitable distances apart along the roof, and one of the bifurcations thereof bent over on one side and the opposite bifurcation on the opposite side,

so that the two vertical flanges of the plate B may be embraced and held in a vertical position against displacement by the clip, as shown at the left of Fig. 1. It now becomes necessary to provide the joint thus formed with a suitable covering to exclude the water and further strengthen the same.

D represents the cap or cover, and is formed of sheet metal with the cut away portions D D D and the projecting portion D, as clearly shown in Figs. 2 and 4, the former figure showing the blank from which the cap is formed and before being bent. The caps are placed upon the longitudinal joints formed as just described, so that the projecting portion D* of one cap will take into the cutaway portion D of the preceding cap, this being allowable by reason of the cut-out portions D D".

It will be seen that in forcing the projection B within the cut-out portion D of the preceding cap the point D of said preceding cap will pass within the cutout portion D of the following cap, whereby a complete water-tight joint is formed without either solder, nails, or rivets.

Cleats may be provided at each side of the transverse seams, whereby contraction and ex pansion are allowable.

Having described my invention and its operation, what I claim is- 1. In a sheet-metal roof, the combination of metal plates flanged to form a joint, with a cap for said joint cut away at each end to interlock with adjacent caps, substantiall y as specified.

2. The combination of the plates flanged, as at B and having the retaining-clips O, with the cap D, cut away, as at D" D D, and having the projecting portions D* D substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

ISAAC H. ASIRE.
